i recently purchased a Lifan Equipsource 2600 Inverter generator. it's very quiet, reliable so far, lightweight @ 68#'s, and.....best of all it was very affordable.
it runs my 13,500 Brisk-Air w/out a hitch. today i'm in a SAM's Club parking lot, it's 100 degrees on the tarmac. i'm cool as a cucumber inside my coach.
i purchased mine on-line for $650+50 ship+no tax.
you can always order from Home Depot for abt $900 if you're afraid of on-line purchases. Home Depot honors most returns.
